Note that the functions of the storage section 210 can be replaced with storage means connected to the outside of the TV 200 or an external storage means (for example, storage means of a cloud server) connected to the Internet 50. Further, there is considered a method of using the storage section 210 built in the TV 200 and the external storage means in combination. For example, there is considered a method of using the storage section 210 as a temporary storage and using the external storage means as a main storage. Such configurations are also included in the configuration examples of the TV 200 according, to the present embodiment.

The communication section 202 is a communication interface configured from a communication device or the like for establishing a connection with communication networks such as the home network 30 and the Internet 50. For example, in the case where the communication section 202 performs wireless communication, the communication section 202 may include a communication antenna for transmitting/receiving a signal used for the communication, a processing circuit for performing various types of signal processing for the communication, and the like. Further, the communication section 202 may be a communication interface for performing communication through wire. In the present embodiment, the communication section 202 is a communication interface for establishing a connection through wire.

The metadata acquisition section 204 has a function of acquiring content information related to content acquired by the content acquisition section. For example, the metadata acquisition section 204 can acquire metadata included in the content acquired by the content acquisition section 206 as it is as the content information. Alternatively, the metadata acquisition section 204 may acquire content information generated by the analysis executed by the analysis section 212 based on the content acquired by the content acquisition section 206. The metadata acquisition section 204 transmits the acquired content information to the PC 100 through the communication section 202.

The content acquisition section 206 has a function of acquiring content provided by the TV 200. For example, the content acquisition section 206 may function as an image receiving section which acquires TV program content by receiving a broadcast wave provided by the broadcast station. Alternatively, the content acquisition section 206 may acquire content provided by being connected to the Internet 50 through the communication section 202.

The analysis section 212 may store the analysis result in the storage section 210.

Heretofore, an example of the function of the TV 200 according to the present embodiment has been shown. Each of the above structural elements may be configured using general-purpose members or circuits, or may be configured using hardware specialized for the function of each structural element. Further, the function of each structural element may be realized by reading out, by an arithmetic unit such as a CPU (Central Processing Unit), a control program from the storage medium such as a ROM (Read Only Memory) or a RAM (Random Access Memory) that stores the control program in which procedures for realizing those functions are written, and by interpreting and executing the program. Therefore, the configuration to be used can be changed appropriately in accordance with the technical level each time when the embodiment is carried out.

5. Outline of UNR Protocol

In the above, the description has been made on the information processing system in which the PC 100 operates the operation of the TV 200. The information processing system is realized by using a protocol (in this specification, this protocol is referred to as UNR protocol) which defines a processing procedure of, between a plurality of devices connected to each other through a network, operating by one device another device, transmitting/receiving information, and monitoring the state.

The UNR protocol is a protocol which is defined such that IP (Internet Protocol) network-enabled devices perform operation between the devices, and thereby enabling the information of the devices, character string information, content information, and the like to be transferred therebetween. Further, the UNR protocol is used between a device having the client function and a device having the server function. In the example described above, the PC 100 has the client function and the TV 200 has the server function. With such a configuration, the PC 100 and the TV 200 can realize each of the functions described above. Hereinafter, the device having the server function in the UNR protocol is referred to as UNR server, and the device having the client function in the UNR protocol is referred to as UNR client.

Here, the UNR server and the UNR client may be associated with each other on a one-to-one basis through a LAN or a Wireless LAN in a home network, for example. Further, a plurality of UNR clients may be associated with one UNR server. Alternatively, a plurality of UNR servers may be associated with one UNR client.

The UNR server and the UNR client can each detect a device to be connected to, and can also each realize a device-control function which is equivalent to that of the infrared remote controller-control, by mainly using a UPnP (Universal Plug and Play) and a IRCC-IP (Infrared Compatible Control Over Internet Protocol) which is obtained by IP-networking an infrared remote controller-control code. Further, the UNR server and the UNR client each realize device control and transfer of information that cannot be realized by the IRCC-IP, by using a CERS-API (Consumer Electronics Remote Service-API). The CERS-API is an API which uses an HTTP request.

Hereinafter, there will be described operation examples of the information processing system according to the present embodiment, which are realized by using functions of the UNR server and the NR client described above.

6. Operation Examples 6-1. Device Connection Operation

First, with reference to FIGS. 5 to 8, operations for connecting devices to each other will be described. FIG. 5 is an explanatory diagram showing an example of a connection device selection screen of the information processing apparatus according to the present embodiment. FIG. 6 is a sequence diagram showing device search processing performed in the information processing system according to the present embodiment. FIG. 7 is an explanatory diagram showing an example of the connection device selection screen including an unregistered device according to the present embodiment. FIG. 8 is a sequence diagram showing device registration processing performed in the information processing system according to the present embodiment.

First, a user M operates the PC 100 which functions as the UNR client, and searches for a UNR server, registers the UNR server, and starts up an application for establishing connection with the server. Hereinafter, the function provided by the application is referred to as remote keyboard function. When the application is started up, the connection device selection screen shown in FIG. 5 is displayed. Here, on the connection device selection screen, there are displayed the devices which have already been registered as devices that the PC 100 can connect to. In the case where the user M wants to register a new device other than the displayed devices, the user M presses “REGISTER NEW DEVICE” button 602.

When the user M presses the “REGISTER NEW DEVICE” button 602, the device search processing shown in FIG. 6 is executed. Referring to FIG. 6, first, when the user M presses the “REGISTER NEW DEVICE” button 602 (S101), the PC 100 transmits a UPnP search message to a device which the PC 100 can connect to through the home network 30, such as the TV 200 (S103). The PC 100 receives a response from each device which the PC 100 can connect to through the home network 30, such as the TV 200 (S105). Then, the PC 100 transmits a “DeviceDescription” acquisition request to the device which has sent the response with respect to the device-search message (S107). A device such as the TV 200 sends back “DeviceDescription” in response to the request of Step S107 (S109).

The PC 100 determines whether each device is a UNR device based on the information included in the acquired “DeviceDescription”. Then, whether the UNR device is registered/unregistered in the PC 100 is determined. Whether the device is the UNR device is determined based on whether an “X_UNR_DeviceInfo” tag is present in “DeviceDescription”. That is, in the case where the “X_UNR_DeviceInfo” tag is present in the “DeviceDescription”, it is determined that the device is the UNR device, and in the case where the “X_UNR_DeviceInfo” tag is not present in the “DeviceDescription”, it is determined that the device is not the UNR device. Further, whether a device is registered/unregistered in the PC 100 is determined based on whether the device is included in a registration list held within the PC 100.

Further, the PC 100 transmits a “CERS_ActionList” acquisition request to the unregistered UNR device (S111). The device which receives the acquisition request of Step S111 sends back “CERS_ActionList” (S113). The above processing is repeated to the device which sends the response, and then the PC 100 generates, and provides the user M with, an unregistered device screen (S115).

Here, FIG. 7 shows the unregistered device screen. In this screen, the unregistered device recognized in the device search processing of FIG. 6 is shown side-by-side with the already registered devices. In this screen, when the unregistered device is selected, the device registration processing shown in FIG. 8 is executed. Here, let us assume that the BDP 300 is in an unregistered state, and there will be described a flow of operation for registering the BDP 300.

For the device registration, first, the user M operates the BDP 300, which is the device to be registered, and gives an instruction to start the device registration (S201). Then, the BDP 300 enters a device registration-waiting state. In this state, the user M selects a BDP icon 603 on the unregistered device screen shown in FIG. 7, and thereby giving an instruction to execute the device registration (S203), the PC 100 transmits a “CERS_API” registration command to the BDP 300 (S205). The value of “registrationType”, initial, indicates that it is a new registration. In response to the command of Step S205, the BDP 300 executes registration processing in accordance with UNR definition. After that, when the PC 100 is notified of the fact that the registration processing of the BDP 300 is completed (S207), the PC 100 generates a screen for notifying the user M of the fact that the registration is completed and provides the screen to the user M (S209).

6-2. Remote Control Operation

Next, with reference to FIGS. 9 to 11, operations for performing remote control of a connection device will be described. FIG. 9 is an explanatory diagram showing an example of the connection device selection screen of the information processing apparatus according to the present embodiment. FIG. 10 is an explanatory diagram showing an example of a remote keyboard function-operation screen of the information processing apparatus according to the present embodiment. FIG. 11 is a sequence diagram showing processing of acquiring a state of the information processing system according to the present embodiment.

When the registration processing of the BDP 300 is completed, there is provided a connection device selection screen shown in FIG. 9, for example. Here, the user M can select a device to be operated. Here, the case where the TV 200 is operated will be described. Accordingly, the user M selects an icon 604, which represents the TV 200, on the connection device selection screen shown in FIG. 9. Then, a remote keyboard function screen shown in FIG. 10 is displayed, for example.

The PC 100 can operate the TV 200 by operating a keyboard in accordance with a keyboard assignment 606 shown on the remote keyboard function screen. For example, when the user M performs remote control operation using the keyboard in accordance with the keyboard assignment 606 (S301), the PC 100 transmits the input key (S303), and the TV 200 operates in accordance with the transmitted key. Further, the TV 200 sends back a response to the PC 100 (S305).

Further, the PC 100 polls the state of the TV 200 at regular intervals by using a “getStatus” action. For example, the PC 100 can perform polling twice per second. For example, in the example shown in FIG. 11, in response to the state acquisition action (S307) from the PC 100, the TV 200 sends “TextInput” representing a character string-input state (S309). As the state of the TV 200, there is considered a currently-viewing state, for example, in addition to the character string-input state. Further, in the case of the BDP 300, there is considered a disc inserted state. The TV 200 may send back one state, or a plurality of states. Alternatively, there is also a case where the TV 200 does not send back a state.

For example, in the case where the TV 200 sends back the character string-input state, the TV 200 is in a state capable of transmitting/receiving a character string. Further, in the case where the TV 200 sends back the currently-viewing state, the currently-viewing state may include class information (such as video, music, and URL) of the content being viewed, source information (such as CD, DVD, BD, Broadcast, ExtInput, and Net) of the content being viewed, information related to reproduction time of the content being viewed, and information of reproduction rate of the content being viewed.

Further, in the case where the BDP 300 sends back the disc inserted state, the BDP 300 may include therein information on the type of the inserted disc, and may transmit the disc inserted state to the PC 100.

6-3. Display Operation of Detailed Screen

Next, with reference to FIG. 10, FIG. 12, and FIG. 13, display operations of a detailed screen will be described. FIG. 12 is a sequence diagram showing detailed information screen-display processing performed in the information processing system according to the present embodiment. FIG. 13 is an explanatory diagram showing an example of a screen displaying detailed information of remote keyboard functions of the information processing apparatus according to the present embodiment.

Further, in the remote keyboard function screen shown in FIG. 10, when the user M presses a “display detailed information” button 608, the content information acquisition processing shown in FIG. 12 is executed. Note that, the content information acquisition processing may be executed at a predetermined timing regardless of whether the user M presses the “display detailed information” button 608, and the detailed information screen may be displayed at a timing at which the user M presses the “display detailed information” button 608. However, here, the description will be continued on the assumption that the processing shown in FIG. 12 is executed at a timing at which the user M presses the “display detailed information” button 608.

When the user M presses the “display detailed information” button 608 shown in FIG. 10 (S401), the PC 100 executes a “getContentInformation” action of “CERS_API” to the TV 200 (S403). In response to the action of Step S403, the TV 200 transmits content information as a response (S405). The PC 100 stores the acquired content information in the storage section 110, and also generates a detailed information screen based on the content information and provides the user M with the detailed information screen (S407).

FIG. 13 shows an example of the detailed screen. For example, the detailed screen can include a viewing-information box 610 containing information on the broadcast program content which is being viewed, a related information box 612 containing related information retrieved from pieces of information inside and outside of the PC 100 based on the acquired content information, and a history box 614 containing history information related to content provided by the TV 200. In the history box 614, history information of Internet applications accessed by the TV 200, and the like are included, for example. When the content provided by the TV 200 is changed, the detailed screen may be updated in accordance with the change.

The PC 100 can activate a browser in a separate window while being in the state in which the detailed screen is displayed. Further, a keyboard is connected to or built in the PC 100. Accordingly, the user M can copy a character string displayed on the detailed screen and can paste the character string in a search box of the browser, for example. In this way, the convenience of using information displayed on the detailed screen is remarkably enhanced. For example, when attempting to use the detailed information displayed on the display device of the TV 200, it becomes unnecessary to perform typing to the PC 100 while referring to the screen of the TV 200.

Further, in the related information box 612, information such as a recommended program based on the content information may be contained. In this case, the information displayed in the related information box 612 may be linked to Internet content. According to such a configuration, the user M can view other content of interest only by clicking the character string displayed in the related information box 612. Further, by clicking information displayed in the related information box 612, the remote control function section 106 may be operated and a channel of the TV 200 may be changed.

Further, the following configuration can also be considered regarding music content played in the TV 200. For example, the content information of the music content played in the TV 200 may be displayed in chronological order in the related information box 612. Further, based on content information of music content a part of which is played in the TV 200, the user M may be notified, using the related information box 612, that a music piece corresponding to the music content or another music piece (with the same artist or genre) related to the music piece is included in the device connected to the home network 30.

According to such a configuration, the user M is made aware that there is a target music piece under management of the storage section 110 of the PC 100 or the DLNA, and it becomes possible that the user M recognizes that the music piece can be fully reproduced. Of course, the related information box 612 may display directly that a music piece which can be fully reproduced is included in the home network 30. The user M, who sees such a display can reproduce and enjoy the music piece later. Note that the location of the music piece (whether it is in the PC 100 or in another device) may be displayed in the related information box 612.

Here, the function of displaying content information of music content in the related information box 612 will be described in more detail.

There is considered a service for searching for a music piece a part of which is played in the TV 200 or a music piece related to the music piece. When viewing the TV 200, we realize that another music piece such as BGM is played during a program, during a commercial, during playback of a BD film, or during playing a game. No attention is paid to such a music piece in many cases, but sometimes, there may be occasions that we feel “nostalgic”, “like it”, “want to listen to it more”, and the like. However, since a music piece like BGM finishes within several seconds in many cases, it may be difficult that the user M who has listened to the music piece finds the music piece by using as a clue a fragment of the music piece that the user M has listened to. Therefore, it is beneficial to the user M that the user M is notified of the information of the music piece played in the TV 200, moment by moment.

Further, many users M each manage music piece data in the PC 100 or the like. In some cases, there may be a user M who manages the music piece data in a device within the home network 30, such as a DLNA server. Further, occasions in which the user M who purchases the music piece data through the Internet 50 are also increasing. For those reasons, the user M may want to know, as information of the music piece played in the TV 200, information as to whether there is the music piece under the management of the user M, whether the music piece is in a state that music piece can be purchased through the Internet 50, and the like. In addition, if the user M can bookmark the music piece that the user M likes among the music pieces played in the TV 200, it can be considered that the convenience is enhanced.

For example, information of a music piece is displayed in the related information box 612 in the mechanism shown in FIG. 14. First, the TV 200 executes a search for the music piece (S1). In this case, for example, the TV 200 accesses a music information providing service through the Internet 50, and searches for the information of the music piece which has been played using the music information providing service. When the desired music piece is detected, the music information providing service provides the TV 200 with a music piece ID of the detected music piece (S2). Next, the TV 200 passes the music piece ID acquired from the music information providing service to the PC 100 (S3). After that, the PC 100 stores the music piece ID acquired from the TV 200 in the storage section 110 or in an external storage means (S4).

Next, the PC 100 provides the music information providing service with the music piece ID acquired from the TV 200 (S5), and acquires the music piece information corresponding to the music piece ID (S6). Then, the PC 100 displays the music piece information acquired from the music information providing service in the related information box 612 (S7). Note that, in the case where the PC 100 acquires a new music piece ID from the TV 200 or in the case where the music piece information is updated in the music information providing service, the PC 100 provides the music information providing service with the music piece ID, re-acquires music piece information, and replace the display content of the related information box 612 with the acquired music piece information. According to such a mechanism, the music piece information of the music piece played in the TV 200 can be displayed in the related information box 612.

For example, as shown in FIG. 15, in the related information box 612, there are displayed music piece information, locations of the music piece, and the like. Note that the PC 100 or the TV 200 can search for the location of the music piece stored in the storage section 110 or in the external storage means of the PC 100 by using the music piece ID. Accordingly, as shown in FIG. 15, the PC 100 can display the detected location of the music piece in the related information box 612. Further, the PC 100 can also use the music piece ID to perform a search as to whether the music piece corresponding to the music piece ID is purchasable through the Internet 50. For example, the PC 100 accesses music piece-selling site on the Internet 50 and searches for the music piece by setting the music piece ID as a search key, thereby detecting whether the music piece is in the purchasable state.

By applying such a configuration, when the user M wants to fully reproduce a music piece played in the TV 200, it becomes possible for the user M to quickly recognize the existence of the music piece, or to quickly purchase the music piece. Further, by pressing a “Bookmark” button in the related information box 612 shown in FIG. 14, the music piece can be easily bookmarked. As a result thereof, the user M can fully reproduce and enjoy the music piece played in the TV 200 anytime the user M likes.

7. Examples of Effects

As described above, according to the information processing system according to an embodiment of the present disclosure, the information based on the operation of the TV 200 can be used in the PC 100, such as the information on a broadcast program to be viewed in the TV 200 and history information of the Internet application accessed from the TV 200.

Further, the PC 100 stores the acquired content information in the storage section 110 built in the PC 100, and thereby being capable of reflecting, on the analysis of user's preference, information such as a program-viewing history and an Internet application-execution history on the TV 200.

Further, the PC 100 can display the acquired content information and the related information retrieved based on the content information on the display screen of the PC 100. Accordingly, the user can see the attached information while continuing to view a program in a full-screen mode on the TV 200.

Further, the PC 100 can activate another application such as a browser in parallel with the detailed screen based on the content information. Consequently, the user M performs copy and paste of any character string from content information, and thereby being capable of easily performing an Internet search and related video reproduction. Further, with the operation performed to the detailed screen, the TV 200 can be operated based on the displayed related information. Specifically, by clicking a character string displayed in the related information box 612, the channel of the TV 200 may be changed to the program that the clicked character string indicates. According to such a configuration, the display can be easily switched to the content of interest while seeing the detailed screen.

Further, also after the TV 200 enters into a standby state or a power-down state and the connection between the TV 200 and the PC 100 is cut off, the PC 100 can update and display the related information box of the detailed screen based on the content information which has been acquired up to then. For example, from the channel information which has been viewed, the content information of the program which can be viewed may be acquired and displayed, based on the current time. Alternatively, there may be displayed a result obtained by a keyword search which is performed based on the title of the program that has been viewed. According to such a configuration, in the case of viewing a sports broadcast, comments on the match or the like is automatically retrieved and displayed.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
